Why require two network interactions to simply find a server?

Why not simply put a single link tag in for each server that you support?

  <link rel="openid.server" href="OPENID.SERVER">
  <link rel="lid.server"    href="LID.SERVER">

If this ever gets to the point where it is unweildy, then one could go
the route of the meta-identity server:

  <link rel="meta.server"   href="META.IDENTITY.SERVER">

I suspect, however, that few of us will find a need for it.
